SPECIFICATION forming part of Letters Patent No. 425,453, dated April 15, 1890. Application filed November Z, 1889. Serial No. 329,019. (No model.)

To all 2071/0772 it may concern-.-

Be it known that I, DAVID O. PAIGE, a citizen of the United States, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in Hanging-Machines; and I declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

In the drawings, Figure 1 is a front elevation of a machine embodying my invention. Fig. 2 is a side elevation of the same. Fig. 3 is a plan view. Fig. 4 is a horizontal section. Fig. 5 illustrates a variation in which the anvil is made in removable sections.

It is the purpose of my invention to produce a machine for turning flanges on large cylindrical rings, more particularly rings that are employed in the construction of large tanks used in the manufacture of beer and other like purposes. Great difficulty has heretofore been experienced in the formation of such flanges on heavy rings of this character,

and they have generally been heated at the edge a little at a time and turned with hammers while the metal was hot. So, also, it has been done by crimping the edge of the metal between two rollers and gradually turningthe edge outwardly. In the former case, however, the process was slow and the work was rough at the best, and in the latter it was impossible to make a flat flange, and in both it was diificult to make a joint with any other similar flange or surface.

In carrying out my invention, A represents the head of a chuck secured to a shaft A and journaled at A A in a suitable bed or frame B.

4 C G represent a case or shell,-within which the cylindrical ring is fastened when it is to have the flanges turned upon it. The shell shown has one of its sections made permanently with, or rather fastened permanently to, the face of the disk as, for instance, the section (E -while the section 0 or other sections are adapted to be shifted out from the center temporarily, in order to facilitate the introduction or removal of one of the metallic rings. This is especially necessary after aflange has been turned. upon one end of the ring and the ring has to be reversed in order toturn the flange at the opposite end.

0 represents blocks located upon the interior of the metallic casing 011 the face of the chuck. They are to facilitate the centering of the ring upon the chuck. Set-screws c render this operation still more accurate. One of the rings is shown in position ready to have the flange turned upon it. It is illustrated by dotted lines in Fig. 4.

0 represents recesses in blocks which are castupon the chuck or upon the interior of the metallic casings. These recesses are designed to receive and form a bearing for the turned flange when the ring is reversed in order to have a flange turned upon its other end; They serve to hold the metallic ring in proper position so that a sufficient amount of the end of the ring will project out from the casing to form the other flange.

I do not limit myself to a construction in which the case or shell 0 G is made in sections, made removable or adapted to shift outwardly to admit a ring, for this case may, if desired, be formed integral with or be attached permanently to the chuck and have a large enough interior diameter to admit the ring after a flange has been turned upon one end. In this event blocks 0 0 may be provided of suitable nature to properly locate and retain the ring Within the case or shell.

lVhen the shell is made as last explained, its outer end may be provided with removable or adjustable segments G which constitute the anvil over and upon which the flange is turned and formed, and pins 0 may or may not be passed through from the exterior to hold the flanged end in place. Such a variation is shown in Fig. 5.

D represents an upright crane. Itis adapted to be revolved horizontally about its axis.

D represents aplane or table in the form of a segment with cogged gearing at its edge engaging and operated by the pinion D This pinion D is operated by means of bevelgearing D actuated by a hand-wheel D or other suitable means. The crane and table are adapted to support the shaft E, which has the flanging-roll E upon its end. E is an adjusting-screw at the end of this shaft, whereby it may be set out farther in the direction of its length, as shown. by the dot-ted lines in Fig. 4, in order to adjust it to its proper position with respect to the flange which is to be turned. E is another adj usting-screw, whereby this flanging-roll may be adj usted in a direction at right angles to its own shaft, and so set in nearer to or farther from the flange that is being turned.

F is an abutment-roll located back of the face of the chuck, in order to receive and sustain the thrust upon the chuck which is given by the turning-roll.

G represents the gearing back of the chuck A.

G is a working pinion which meshes with this gearing, and is in turn driven by the cogwheels or other suitable gearing G which are connected with the driving-belts. I would, however, have it understood that any suitable gearing may be employed instead of the particular gearing shown.

H is a bridge or support between the main frame and the upright crane. The crane may be adjusted to any particular position by reason of the fact that it is sustained by bolts a, engaged in intersecting grooves 12, formed in the base-plate. It is now apparent that if it is desired to operate upon a longer cylindrical ring it is only necessary to lengthen out the shell 0 Othat is to say, to employ a new shell of suitable sizeand adjust the crane on the base-plate and put in a corresponding bridge II. This shell or case 0 O at its outer edge is so shaped as to form an anvil, upon which the flanging-roll turns the edge of the metal in forming the flange.

To operate this device, the cylindrical ring upon which the flanges are to be turned is introduced and properly adjusted into the cylindrical case 0 0, sufficient projecting beyond the end ofthe cylindrical case to form the flange. The flanging-roll is them properly adjusted in position and the chuck is set in motion. ing-wheel, gradually turns the flange as the cylindrical ring is revolved. It is apparent that he 'soon turns it down upon. the outer ends of the cylindrical case as an anvil, and that the metal is manipulated cold and requires no heating for this purpose. As'the flange is being turned, it is apparent that the flangingroll may be adjusted in or out or nearer to or farther from the ring, to conform at all times to the requirements of the work.

In using the term metallic shell or case in the claims I would be understood as meaning either the form in which the shell or case is itself made in segments adapted to shift to or from the center of the chuck or a shell permanently secured and with adjustable an- The -operator then, with the flangvil portions at its end. Of course both the is turned, an adjustable vertical crane, an

adjustable flanging-roll carried by said crane, and an abutment-roller located back of the chuck to receive the thrust of the flangingroll, substantially as described.

2. In a machine for turning flanges upon large cylindrical rings, the combination .of a chuck, a case or shell adapted to inclose the ring and provided at its outer end with an anvil-surface upon which the flange is turned, the blocks 0, for centering the inner end of the ring, the crane provided with a flangingroll, and the abutment-roll located back of the chuck, substantially as described.

3. In a machine for turning flanges upon large cylindrical rings, the combination of chuck, a case or shell adapted to inclose the ring and provided on its outer end with an anvil-surface upon which the flange is turned, channeled blocks for centering the inner end of the ring and for receiving the turned flange on one end of the ring, a crane, a flanging-roll carried by said crane, and means for adjusting the flanging-roll, substantially as described.

4. In a machine for turning flanges upon large cylindrical rings, the combination of the chuck, the cylindrical shell or case adapted to receive the ring, adjustable sections forming part of the outer end of said casing andv removable for admitting or removing the cylindrical ring, and a crane carrylng a flanging-roll, substantially as descrlbed.

5. In a machine for turning flanges upon the flange is being turned upon the other end of the cylindrical ring, substantially 'as described.

6. In a machine for turning flanges upon roll and means for operating the said crane,

and an abutment-roll located back of the face of the chuck for receiving the thrust of the flanging-roll, substantially as described.

In testimony whereof I sign this specification in the presence of two witnesses.
